Final answer:
Otto von Guericke conducted the Magdeburg hemispheres experiment to test Aristotle's beliefs on vacuums, demonstrating the power of atmospheric pressure.
Step-by-step explanation:
Otto von Guericke conducted an experiment known as the Magdeburg hemispheres to test Aristotle's belief on the nature of vacuums. He created two large metal hemispheres and sealed them together, removing the air inside. Then, he used horses to try and pull the hemispheres apart, but they were unable to, demonstrating the power of atmospheric pressure. This experiment challenged Aristotle's belief that nature abhors a vacuum.
